Experimental Information:

X-RAY DIFFRACTION

Space Group:

H 3 2

Cell Constants:

a = 76.81   b = 76.81   c = 85.9 (Ångstroms)

α = 90.0   β = 90.0   γ = 120.0 (degrees)

Refinement:

The structure was refined using the CNS 1.2 program. The R value is 0.23 for 4592 reflections in the resolution range 30.0 to 2.2 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
